Abstract: A two-dimensional finite-element simulation consumes less computational resources and has higher efficiency than a three-dimensional simulation. However, the existence of great differences between different slice images ...

Abstract: The mesoscale structure of asphalt mixture in finite-element (FE) models has been widely used in evaluating crack growth and fatigue performance. However, the present methodology for establishing the mesoscale structure ...

Abstract: The obvious nonlinear characteristics of fatigue damage accumulation for asphalt binders can be induced by variable amplitude loading. However, the corresponding nonlinear characteristics are difficult to be characterized ...

Abstract: Top-down cracks (TDCs) and their associated secondary damage have emerged as critical factors limiting the long-term service performance of flexible asphalt pavements. The mechanisms underlying various types of TDCs, ...

Abstract: Based on the long-term maintenance data, the performance and service lives of several orthotropic steel bridge deck (OSBD) pavement materials in long-span suspension bridges were studied and evaluated. According to the ...

Abstract: The reclaimed asphalt pavement materials have been used for sustainable cold-recycling, significantly benefiting air quality and resource conservation, while its microscale interface properties greatly affected road ...

Abstract: This study investigated the common aging protocols for binders and asphalt mixtures on fine aggregate matrix (FAM). Currently, no unified aging protocols are specified for laboratory-prepared FAM. The majority of FAM-related ...

Abstract: This paper evaluated the effectiveness and cost-effectiveness of pavement treatments based on the equivalent area method, which uses the area bounded by posttreatment performance curve, threshold, and unified standard ...
